Zap Voicer - Audio as Voice

Send local audio files and audio catalog memes as native voice messages on WhatsApp Web.

# Zap Voicer - Audio as Voice ## What the Extension Does Transforms local audio files (MP3, WAV, and OGG) and audio catalog sound memes into native voice messages on WhatsApp Web. Select an audio file from your computer or search for sounds online, and the extension injects the content directly into WhatsApp’s recording flow, sending it as if it had been recorded through the microphone at that moment. ## Why You Should Install It ### Professional Quality Send voice-overs, recorded replies, music tracks, or pre-produced content with consistent quality and no unwanted background noise. ### Productivity and Speed Record complex messages once and reuse your audio whenever needed. Access the file picker through the button integrated into the message composer or by using dedicated keyboard shortcuts. ### Integrated Sound Library Search for memes, sound effects, and popular audio clips in real time directly from the conversation. Preview sounds before sending them and quickly switch countries to explore global trends. ### Native Experience Recipients receive the content exactly like a voice message recorded through WhatsApp, including native playback-speed controls (1x, 1.5x, and 2x) and continuous playback. ### Customization and Control Configure individual keyboard shortcuts for local files and sound search, enable automatic volume normalization, adjust the silence trimmer, and use an optional artificial delay to simulate natural pauses before sending. ### Privacy and Security All processing takes place locally in your browser. Your files are not uploaded to third-party servers; transmission occurs exclusively through WhatsApp Web’s own infrastructure. ## Key Features - Support for local MP3, WAV, and OGG files - Integrated audio library with debounced real-time search - Collapsible vertical menu with country selection for trends - Audio preview button (play/pause) with secure decoding through Blob URLs - Configurable silence trimmer with adjustable sensitivity threshold and breathing margin - Zero-latency instantaneous audio stream injection for immediate transmission - Buttons integrated into the message composer, positioned to the left of the native microphone and unaffected by hover-related layout shifts - Customizable keyboard shortcuts (Alt+A for local files and Alt+M for sound search) - Direct access to the settings page by clicking the extension icon in the browser - Animated one-time modal presenting the latest version updates - Intelligent volume normalization using the Web Audio API - Hands-Free recording simulation integrated into the original interface - Manual cancellation with immediate audio interruption - Dynamic support for WhatsApp Web’s Light and Dark themes Designed for everyday messaging, providing seamless voice audio playback directly into WhatsApp Web conversations. --- ## Release Notes ### Version 1.4.0 - Unified single action button in chat composer displaying the official icon - Local audio file upload integrated directly into the audio catalog modal header - New navigation tabs: "Trending", "Recent", and "Favorites" with live counters - Stack-based (LIFO) recent sounds history with automatic deduplication - Favorites bookmarking with golden star and drag-and-drop reordering - Silence trimmer connected to the sending pipeline, with configurable activation, sensitivity threshold, and breathing margin ### Version 1.3.1 - New high-definition vector SVG official logo and refreshed extension icons - Direct access to the options and configuration page by clicking the extension icon in the browser toolbar - Animated modal dialog highlighting recent updates, displayed once per version update - Enhanced sound preview stability with instant Blob URL playback and secure release - Automated obfuscated packaging workflow with XML token mapping ### Version 1.3.0 - Complete multi-language support (i18n) powered by the `chrome.i18n` API (English, Portuguese, Spanish, French, and German) - Automatic browser language detection with unified locale dictionary files - Refactored and modularized settings UI and toast notifications for all supported locales - React 18 event compatibility fixes for WhatsApp Web message composer interaction ### Version 1.2.1 - Adaptive silence trimmer using RMS energy analysis to remove empty silence from audio start and end - Improved PTT (Push-To-Talk) native voice recording emulation with instant audio stream feeding - Fixed layout shift issues when hovering near the native microphone button - Enhanced error handling with discrete contextual floating notifications ### Version 1.2.0 - Rebranded as Zap Voicer with revamped UI components - Integrated sound effects and meme search engine directly into the chat interface - Country selector dropdown to browse trending audio clips by region - Customizable global keyboard shortcuts for local files (`Alt+A`) and online sound search (`Alt+M`) - Audio volume normalization engine via Web Audio API (`AudioContext`) - Optional pre-send artificial pause delay setting ### Version 1.0.0 - Initial public release of WhatsApp Audio as Voice extension - Injection of local MP3, WAV, and OGG audio files into WhatsApp Web recording pipeline - Interception of `navigator.mediaDevices.getUserMedia` for seamless native voice transmission - Dark and Light theme detection and dynamic style adaptation
